Vergil is not a misanthropist. This is a partial text from Trinity of Fates where explains Vergil doesn't hate humans:

"Dante's older twin brother. In contrast to  Dante , he is the type who dislikes a commotion. He seeks power as a demon successor to Sparda, and plots to open the gate to the demon world with Arkham. However, Vergil is also a successor to Sparda's bloodline. Certainly, it is not the case that he desires demonic power in order to invade* the human world - his desire for power comes from a genuine feeling of wanting to become stronger. As a result he is used by Arkham, and he alone falls into the demon world, where he challenges Mundus to battle, but is defeated.


 * Invade, raid, or show agression towards. That is to say, Vergil has no aggressive intentions towards the human world. "
